ELASTIC HOLDER FOR LAIIIP-S-HADES AND LAMP-GLOBES.

Application filed March 26, 1920.

To all whom it may concern:

Be it known that I, KARL BALTHASAR ScI-IAFER, a citizen of the German Republic, and residing at Diisseldorf-Holthausen, Germany, have invented certain new and useful Improvements in Elastic Holders for Lamp-Shades and Lamp-Globes, of which the following is a specification.

The present invention relates to an elastic holder for lamp-shades and lamp-globes and consists in the hereinafter described peculiar arrangement of the edge of the holder, by which the lamp-holder itself is converted into an elastic carrier for the lamp-shade, and is adapted to release the shade on a simple pressure with the fingers of one hand only, or to open, respectively, for receiving the shade, without any other part or manipulation being required. As the new holder may be made in one piece, both its manufacture and its use are extremely simple.

In the accompanying drawing Figure 1 is a perspective view of the new lamp-holder showing its manipulation. Figs. 2 and 4. are sections through the holder in two difierent operative positions, Figs. 3 and 5 are sections on the lines A-B and C- l), respectively, through the holders in the positions shown .in Figs. 2 and 4:, respectively. Fig. 6 is a modified form of the holder, shown partly in section.

To the yoke a is attached in any suitable manner a holder ring 6 of angle section and made of elastic material. The cylindrical flange Z) of this ring is undulated at its edge, so that broad portions (Z and narrow portions f are formed. The broad portions (Z are slightly curved inward and do not verge into the disk-shaped portion of the ring, but are extended upward and doubled over thus forming doubled projections g, the upper edge of which is likewise undulated, these undulations It being of an opposite sense to those of the flange at cl. The diskshaped portion 2' of the ring may be made in one piece with the cylindrical flange, as shown in Figs. 15. The cylindrical flange with the portions (Z and 9 may, however, also be separately formed and secured to said disk-shaped ring 2'.

An inward radial pressure against the portions g will force the portions (Z outwardly,

spreading them as shown in Fig. 4E. The radial spreading of the portions at is possible because the extending of the periphery of the cylindrical portion caused thereby is compensated by the simultaneous radial inward contraction of the narrow portions f of the flange (Figs. 4, 5). The necessary radial pressure against the extensions 9 may be effected simultaneously by the fingers of one hand. The portions (Z will then spread in such a manner and to such an extent, that the rim of the shade may be engaged into the holding ring (Fig. 4:). As soon as the portions 5/ are released, the undulations d spring back and engage over the rim of the shade, holding the same in position.

The modified form of the ring according to Fig. 6 acts in the same manner; here the undulated cylindrical ring is made in one piece with a holder cap 70.

I claim:

1. In combination with a lamp socket, a shade holder engaged therewith, and including an elastic ring, having circumferentially spaced flanged portions on its perimeter, extending upon opposite sides of the ring, and in substantially parallel relation to the ring axis, said flanged portions capable of being radially flexed to clampingly engage one edge of each flanged portion with the lamp shade or disengage the same from said shade.

2. In combination with a lamp socket, a shade holder engaged therewith, and including an elastic ring having a continuous flange on its perimeter with portions thereof projecting in relatively opposite directions from said ring, the flanged portions extending upon one side of the ring, adapted for clamping engagement with the lamp shade, and being releasable by an inward radial pressure upon the corresponding portion of the flange projecting upon the opposite side of the ring.

3. In combination with a lamp socket, a shade holder engaged therewith, and including an elastic ring having portions bent upon themselves, and extending from one side of the ring, the free edges of said bent portions extending beyond the opposite side of the ring and inwardly curved to engage a lamp shade, said bent portions of the ring affording finger engaging parts, whereby the ring may be radially flexed and, operatively engaged with or disengaged from the lamp shade.

4%. As anew article of manufacture, a

5 shade holding element for lamps, consisting of a resilient disk having oircumferentially spaced portions each extending upon relatively opposite sides'of the plane of said disk and radially yieldable by an inward 10 pressure upon said portions at one side of the disk to engage said portions at the opposite side of the disk with the lamp shade, or disengage the same therefrom.

In testimony whereof I aflix my signature in presence of two witnesses.
